Re: Agilent 82357B repeatable hard failure

Hi Michael,
Could you please capture the usb traffic with Wireshark or usbmon for this
onebyte run.
Judging by this output maybe your board behaves differently from Jim's and
Micha's but we would like to check.
Each line of the decode below shows the character read, ascii code of
character decoded as ADSR and ibsta decode.
It looks like the ibsta corresponds to the* next *character read
interpreted as ADSR.
So it might be that the instrument has already latched the next byte on the
bus when the ibsta of the board is taken after the previous read.
Could you do a onebyte run with a different instrument too please ?
No need to take the usb traffic for that also.
Thanks,
-Dave
